Lacroix entered his guilty plea today before U.S. District Court Judge Mark Wolf of the District of Massachusetts.

According to the plea agreement, b etween May 2011 and May 2013, Lacroix obtained and possessed payment card data for more than 14,000 unique account holders.

Lacroix also admitted to hacking into a computer server operated by a local Massachusetts police department in September 2012, and then accessing an e-mail account belonging to its chief of police.

Additionally, Lacroix admitted to repeatedly hacking into law enforcement computer servers containing sensitive information including police reports, arrest warrants, and sex offender information, between August 2012 and November 2012.

Lacroix also admitted to using stolen credentials to access and change information in the servers of Bristol Community College on multiple occasions between September 2012 and December 2013.

Judge Wolf set Lacroix’s sentencing for Oct. 27, 2014.

The case was investigated by the FBI Boston Division Cyber Task Force.

The case is being prosecuted by Senior Trial Attorney Mona Sedky from the Criminal Division’s Computer Crime and Intellectual Property Section and Assistant U.S. Attorney Adam Bookbinder of the District of Massachusetts.
